Hermione Granger: It’s not going to work.

Fred Weasley: Oh, yeah?

George Weasley: And why is that, Granger?

Hermione Granger: You see this? This is an Age Line. Dumbledore drew it himself.

Fred Weasley: So?

Hermione Granger: So… a genius like Dumbledore couldn’t possibly be fooled by a dodge as pathetically dimwitted as an Aging Potion.

Fred Weasley: But that’s why it’s so brilliant.

George Weasley: Because it’s so pathetically dimwitted. Ready, Fred?

Fred Weasley: Ready, George.

Fred and George: Bottoms up.

(They jump into the Age Line and get their names into the cup, but it backfires, turning them old…)
